Pursuing education overseas is a high impact practice in higher education. Students who identify as LGBTQIA + --commonly referred to as "queer," an umbrella term--may be more likely to participate yet face additional unique challenges. Using a systematic review of literature across multiple disciplines, this paper explores LGBTQIA + students' motivations, identity development, and university experiences while participating in education overseas. It also aims to define the term "queer international student" and examines the theoretical frames used to understand this population in the literature. Findings show that literature carves out a composite of students who view, and sometimes actively seek, overseas education to develop themselves, express their identities, and live in communities that are more welcoming and safer than those at home. However, they also face conflict in English language classrooms, on campuses, and with their families as they navigate expectations, with some switching between cisheteronormative and queer identities in different communities. On university campuses, scholars noted, queer international students can be viewed singularly as international students, with their sexual orientations and other intersectional identities going unrecognized or being erased. Moreover, higher education scholars and practitioners often do not designate--or perhaps exclude--international students in studies and programming for LGBTQIA + students. As a result, queer international students may not feel like they belong in any group and risk being double-marginalized in higher education. This paper concludes with five recommendations for additional research in this emerging subfield of higher education literature.
